I believe this is right. Although, the game before the super bowl, Brady had a small injury and had to be pulled from the game. Bledsoe went back in, won the game and got the Pats into the superbowl. It was the last time he ever played as a patriot. Brady returned as a starter in the superbowl, and the pats won their first superbowl with brady as their new QB.

I think the mentor thing is so overrated. Did Peyton or Luck need to learn from a veteran QB? I think the most valuable thing Brady learned in his 1 year as a backup was just how to run the offense. That way once he came in he didn't have to learn on the fly and at least had some experience from practice. I think he would have been just as successful long term without Bledsoe, but maybe his time as a backup better prepared him for when he first came in.
